Pump Repair

Pumps are often at the heart of your process.

Periods of lower output or downtime are unacceptable.

Your production relies on them, you want a professional uncompromising service, with confidence that performance will be restored on time, and at the quoted price.

North Ridge Pumps offer pump maintenance and repair for owners of all types of centrifugal, rotary, and reciprocating positive displacement pumps of any brand. Your pump may only need a basic service including gaskets and a mechanical seal, alternatively it may require a major overhaul of all internal parts, with root failure analysis and monitoring installed.

We provide all levels of service, whether your pump has been damaged during operation or been left idle for long periods without maintenance, we will a perform a thorough inspection before performing any work, once approved all pumps are repaired and tested before returning to site.

Outsourcing pump maintenance and repair ensures your pumping equipment is maintained and restored back to its original or improved specification, in line with manufacturers guidelines by dedicated pump professionals.

All repairs are supplied with a 12 Month Warranty on parts that have been replaced, providing recommended interconnecting parts are substituted. Coatings can be applied to improve efficiency, or where lead times may be excessive on urgently required parts, materials can be rebuilt or machined to suit.

We are here to be as versatile as you need us to be. We are able to disconnect, collect, inspect, repair and return your pump to your works swiftly, ensuring you are without your unit, or back up for long periods of time. Alternatively, you are able to to drop your pump to our works for the repair to be undertaken.

On receipt a detailed inspection report is compiled and supplied prior to work being undertaken, clearly outlining any recommendations or work to be undertaken ensuring transparency in our work.

We will advise whether your unit is beyond economical repair and requires replacing. If your process is without a spare pump, we recommend a new unit be ordered with the old unit repaired and be kept as an emergency spare as in this case study.

Once a repair has been completed all pumps are tested hydrostatically and run tested to ensure they operate as required.

North Ridge offer a process review which we often recommend during our failure diagnosis stage. Perhaps your process has changed, but your pump has remained unaltered, or the rate at which an application is undertaken, its demands or process liquid has been modified and your unit will not prevail.

North Ridge are here to provide a comprehensive process review, guide the way forward, selecting the most appropriate technology and work together to ensure your process runs uninterrupted, and your outcomes delivered.


What is Your Repair Process?

North Ridge can offer a variety of outcomes dependent on your situation. Firstly, we can disconnect and return your pump to our works for inspection, simply collect your unit or it can be shipped to us.

If you are aware of what is wrong with your pump, we can provide an estimate pending visual inspection, and this will be verified upon receipt.

North Ridge offer a full inspection, report, and cost for rectifying your pump to restore it back to full working order. We will advise if it is beyond economical repair and recommend if any changes are required for your process or application.

Some users often prefer for a pump to be repaired, as well as purchase a new unit so they have spare capacity in the event of breakdown. This can be crucial in applications with high processing volumes with a large associated cost of downtime.

What type of pumps do you repair?

We repair all types of centrifugal, rotary, and reciprocating positive displacement pumps. We do not repair vacuum pumps.

What Warranty is offered with pump Repair?

We offer a 12-month Warranty on parts that have been replaced. As it is not possible to determine the age of all parts, hours of use or true working conditions, we are unable to offer a warranty on parts not replaced at the time of repair.

As successful operation of the pump is based on a number of parts working together, the warranty issued is based on all the recommended spares being replaced.

How will you decide whether to repair or replace the pump?

This is a complicated issue due to several factors such as pump age, application, size, cost of replacement, associated downtime, and how quickly a repair or replacement is needed.

Once we have inspected your pump, we provide a full report ensuring transparency in our assessment of the condition of internal parts and talk through what we believe is best for your process.

How long will my repair take?

This will depend on the lead time of parts, the condition of the pump and associated parts. For us to understand fully, we need to inspect the pump to then understand which parts are required and the associated lead times.

Can you improve the efficiency?

There are several changes we can make to improve the efficiency of the pump, but a pump is only as efficient as its operation within a process. For us to improve its efficiency, firstly we need to understand its operation within your system, and then determine what changes may be required to optimise efficiency.

If your pump was purchased prior to 2011, it will most likely have a low efficiency IE1 motor, which can be replaced with a higher efficiency version, however this efficiency gain can be insignificant if the pump is operating at the wrong area on the curve.

It may be a good opportunity to reevaluate your process, which may have changed since the pump was originally supplied.

Do you test Pumps?

Pumps are run tested to ensure units will operate as intended once reinstalled. Hydrostatic testing will also be performed to ensure all seals are correctly seated. Tests are dependent upon the installed motor being returned to us.

Performance tests are available at extra cost which varies according to size and type of unit.

How can I Maintain my pump sufficiently to avoid sudden pump failure?

There are two ways to do this. The first is to regularly inspect the pump frequently for leaks, vibrations or abnormal noises and check for wear on components by dismantling the pump.

Another option which is much less labour intensive, is to have pump monitoring installed. We monitor your unit 24/7 for abnormalities, and our monitoring equipment is accurate enough to determine pump failure between 3 and 12 months in advance of failure avoiding downtime, frequent unnecessary inspection and unscheduled stoppage.

Maintenance engineers are free to work on projects proactively, with significant cost savings made not only through avoidance of downtime, but avoidance of expedited deliveries such as airfreight charges, expedited production charges and time spent troubleshooting.

Diagnosing what may be wrong with your pump often starts with our troubleshooting guides. This can be the most cost effective way of determining what may be causing loss of output pressure, flow, pump wear, tripping, strange noises or leaking.

Our guides provide indications of how to solve various issues, but also areas of your system which may need investigating, as most pump failures are directly related to system issues.
